This paper studies the pressure distribution on the forearm and the hand palm during ambulation with forearm crutches. It also presents the design, modelling and development of a forearm crutch that is capable of eliminating the high pressure induced on patient's palm and forearm areas while gating; preventing other injuries to the nerves and muscles of the mentioned extremities. Eventually, one of the main objective of conducting this project is to make the patients feel less tired and more comfortable during crutch-aided ambulation. The design of the crutch is drawn using CATIA software, a CAD modelling package. The study on the developed design is to prove that it is of high quality and is more comfortable compared to available regular forearm crutches. It is developed using two experimental methods, namely: Energy Expenditure Index (EEI) and Electromyography (EMG). The experiments related to the mentioned methods have been conducted with the help of 10 healthy/normal volunteers. Also the crutch parts have been simulated using COMSOL Multiphysics Software. Lastly, a survey was prepared and its results are also provided in accordance with the way the patients feel about the developed design. The results of all four methods mentioned, show that the focal pressure on the patient's hand and forearm has been significantly reduced; also, the energy expenditure level has been dropped. It can be concluded that the developed crutch is of high quality and is more comfortable compared to regular forearm crutches. © 2016 IEEE.
